ABSTRACT:
A large loop or ring of spring steel, which is rectangular in cross section, has two separable ends, one of which is releasably securable in a recess in the other by means of a removable shackle or wire snap. A plurality of key blocks are removably mounted on the ring for sliding movement thereabout coaxially of the ring. In one embodiment the ring is solid and projects slidably through a corresponding rectangular recess which extends centrally through each key block; and in a second embodiment the ring is hollow and the blocks are slidably mounted in the rectangular bore of the block. Numeral-bearing tags are secured to the faces of the blocks in each embodiment; and in the second embodiment an arcuate opening is formed in the front wall of the ring so that the tags on the blocks will be viewable through the opening. A small swivel ring projects from the underside of each key block to have a key secured thereto by a wire snap. The blocks come in various colors so that their identification may be listed in a master log book containing colored sections with numbered lines for recording key vs. lock information, such as: number, location, name or names of persons with keys, location and number of duplicates, etc.
